Detailed Description

This board is describes the Sensor Terminal Board from Dresden Electronic. It is a carrier board for the RCB family.

The Sensor Terminal Board is a carrier board for the radio controller board family.

The wiring of this module is very specific; normally, all the functionality on the Sensor Terminal Board (FTDI, LEDs, button) is controlled by memory-mapped IO, using the external memory interface of the ATmegas. This is not possible with the ATmega128RFA1 as it does not feature an external memory interface. For that reason, GPIO lines have been re-wired to allow an external memory interface emulation. The schematics of the RCB128RFA1 document the following wiring:

XTAL1           EXT0.7          CLKI

In addition, the standard STB pin mapping is retained for:

PE7 FT245 /RXF PE6 FT245 /TXE PG2 ALE

The STBxxx has memory mapped LEDS and Keys. KEY: memory mapped on external memory bus address 0x4000 LEDS

You can select between using the LEDs on the RCB or on the STB. In order to use the RCB LEDS, you have to define the macro USE_RCB_LEDS.

The LEDs on STB have a write-only memory interface, so we can't read back the LED status. So we need to have a shadow register, which stores the current LED state. Since the board interface consists only of a header file, we use register GPIO2 on ATmega128RFA1 for shadowing, because it would be hard to ensure the single instantiation of a global variable from a header file, which is used in many module files.
